AJ MacGinty is to leave Connacht at the end of the season to join Sale Sharks.
MacGinty moved to Connacht following the World Cup but he will leave the Sportsground in the summer to make the switch to the Aviva Premiership.
"I am very excited to be joining Sale Sharks next season. They are a club with great ambitions, and I look forward to the challenges that lie ahead," MacGinty said.
"I have really enjoyed my time at Connacht and would like to thank all the coaches, players, fans and staff for their support. In particular, I would like to express my gratitude to Pat Lam (Connacht head coach), and I look forward to finishing the season as strong as possible."
Born in Dublin, MacGinty attended Blackrock College before moving to the United States and he featured in all three of their pool games at the 2015 Rugby World Cup.
Sale rugby director Steve Diamond told the club's official website: "We were alerted to AJ during the World Cup, and we have been watching his performances at Connacht.
"He is great in defence and has an 80% success-rate kicking his points.
"I am sure that when he works with Paul Deacon (Sale's attack and skills coach) he will become the finished article.
"He will be a great addition to the squad, and we are looking forward to AJ joining us pre-season."
